How can a mail processor identify potentially suspicious packages?

Identifying potentially suspicious packages involves evaluating several physical characteristics that may indicate a risk. When checking for unusual shapes, odors, or excessive weight, mail processors can spot packages that deviate from standard expectations. For example, a package that is unusually shaped may not be expertly packed, which can be a warning sign. Similarly, strange odors could suggest the presence of hazardous materials or other threats. Excessive weight can also be a concern, as it might indicate that the package contains dangerous items or is filled with substances that should not be on a mail conveyance. These factors collectively help to assess the safety and security of the mail being processed.

The other options relate to procedural checks but do not specifically address features that might raise immediate red flags about the contents of a package. Proper postage is essential for ensuring delivery but does not indicate the package's safety. The duration that a package has been in the facility and ensuring correct recipient information are important for operational efficiency and accuracy, but they do not directly identify risks associated with the physical attributes of a package.
